Dear Market Participants,

In order to maintain maximum security of our IT systems, we need to upgrade the version of the TLS protocol on the input side to the version TLS 1.2.
TLS protocols TLS 1.0 and TLS 1.1 in automatic SOAP communication in the direction from the participant's system to the CS OTE system will be no longer supported from October 23, 2019.
Market Participants accessing the CS OTE via web browser will not be affected by this change

We strongly advice you to check your system settings, or please contact your IT specialist for this purpose..

Thank you for your understanding and we apologize for any inconvenience.

Petr Smrček, Head of IT Management Department
